GENERAL DESCRIPTION
FEATURES
The ICS8302 is a low skew, 1-to-2 LVCMOS • 2 LVCMOS / LVTTL outputs
Fanout Buffer and a member of the
ICS
• LVCMOS / LVTTL clock input accepts LVCMOS
or LVTTL input levels
HiPerClockS™
HiPerClockS™family of High Performance
Clock Solutions from ICS. The ICS8302 has a
single ended clock input. The single ended clock
• Maximum output frequency: 200MHz
• Output skew: 25ps (typical)
input accepts LVCMOS or LVTTL input levels. The ICS8302
features a pair of LVCMOS/LVTTL outputs. The ICS8302 is
characterized at full 3.3V for inputVDD, and mixed 3.3V and
2.5V for output operating supply modes (VDDO). Guaran-
teed output and part-to-part skew characteristics make
the ICS8302 ideal for clock distribution applications demand-
ing well defined performance and repeatibility.
• Part-to-part skew: 250ps (typical)
• Small 8 lead SOIC package saves board space
• Full 3.3V or 3.3V core, 2.5V supply modes
• 0°C to 70°C ambient operating temperature
• Lead-Free package available
• Industrial temperature information available upon request
